APPLICATION OF BUILDING INFORMATION MODELLING (BIM) IN ARESIDENTIAL PROJECT IN INDIA: BENEFIT-COST ANALYSIS

Building information modelling (BIM) is becoming a better-known collabora-tion process in our construction industry. BIM is a systematic process thatamalgamates all the other geometric computer-generated models, or data thatcreates simulations that can be used for the project manager, owners, facilitymanager or other parties to look after the project and deliver the project moreefβiciently. The implementation of BIM in India is still at a nascent stage due toa lack of knowledge of the advantages of BIM. Moreover, there have been only afew case studies conducted in India about BIM; therefore, the principal agendaof this study is to enlighten the readers about the beneβits accrued if BIM isapplied, in the residential project, before the construction. Hence, the authorshad taken a residential project located in Gujarat, India, for a case study. The3D and 4D models of the project were generated; 8 errors were identiβied thatcould have been detected before construction if BIM had been applied. Thecost needed to make a BIM model was|171,050. Whereas, the amount thatcould have been saved if BIM was implemented beforehand was discovered as|246,773. Consequently, the beneβits to cost ratio for two weeks in delay wasdetermined as 1.44. It can be recognised as the beneβit of utilising BIM for con-struction.
